inflated, the greatest depth con- 

 tained slightly more than two 

 and one-half times in the length 

 of the same. Caudal tibiae 

 compressed, V-shaped in section, 

 the dorsum deplanate, nonsul- 

 cate, the margins elevated and 

 closely serrate, dorso- and ventro- 

 external distal spurs subequal in 

 length, medio-external nearly 

 twice the length of those dorsad 

 and ventrad of it, internal spurs 

 all longer than the external spurs 

 and as in the generic diagnosis; 

 caudal metatarsus armed on 

 the dorso-internal margin with 

 eight to nine spines, on the 

 dorso-external margin with 

 nine to ten spines.

Description of Allotype. — - 

 Agreeing with the female lecto- 



type except in characters here mentioned. Pronotum of male more 

 produced caudad and more ampliate in the same direction, the 

 cephalic width contained one and one-half times in its greatest 

 length, the greatest caudal width subequal to its length; cephalic 

 margin as in female, caudal margin strongly arcuate laterad, arcuato- 

 truncate mesad; lateral lobes as in the female. Tegmina well 

 developed for this group, projecting caudad of the pronotum a 

 distance which at its greatest is subequal to the greatest length of the 

 pronotum, broad, the width of the dorsal field of a single tegmen 

 subequal to the greatest width of the pronotum; lateral field deep, 

 slightly less than half the width of the dorsal field; distal extremity 

 of dorsal field well arcuate; speculum of tegmina subequal in width 

 to the cephalic margin of the pronotum. Subgenital plate with the 

 distal margin complete.
